TO ALL WHOM IT MAYv CONGERNz Be -it known that-LJAMES T. WHIPPLE, ofChicago, in the cotinty of'Cook, and State of Illinois, have invented anew and useful Improvement in Well-Tubing; and I do hereby declare thatthe following is a full and egract description thereof, reference beinghad to the accompanying drawings, and to theletters of reference markedthereon, making a part 4of this specification, inwhichn.

Figure 1 isa perspective view of the outside of the tube, and

Figure 2 is a` central transverse vertical section through the same.

Similar letters of reference, where theyocc'ur in the separate figures,denote like parts in eachof the` drawings. 4 Y

My invention relates to an improvement in that class of Wells thatismade by sinking a vhollow tubeinto the ground to anygivendistance,'and the nature of my improvement consists in a device, or, inother words, a valve within a-cylinder, which is placed within` the mainpipe at any required distance fromthe surface of the ground. Saidcylinder is so constructed as to form a Water-tight joint between itssides and the sides of the main pipe, by means' of a suitable packing,or other ways, also receiving the operating or suction-valve, which isconnected to the handle of the pump by means of'al connecting-rod,'whereby the water can be raised a greater distance than with the commonsuction-pump, as will be more fully explained by the descriptionhereinafter given.

It is found in the constructing of tubular wells, that, bythe resistanceof the screen or4 lter, the water i cannot be raised by the commonsuction-pump to a distance greater than fromVtwenty-iivc to twenty-eightfeet; therefore it is necessary to excavate the earth (for the purposeof attaching the pump) to a distance suiiicient to leave onlytwenty-five or twenty-eight feet between the pump-valve and the bottomofthe well. But by the use of my arrangement this difficulty ispractically overcome, as the valve may be placed at any requireddistance from the bottom of the well, to admit of the water being drawnto the valve by suction,'and, as the same passes through and above thevalve, it is lifted or forced the remaining distance to the spout of thepump. i Toenable others skilledju the art to construct and use myinvention, IV will proceed'to describe the same with reference to thedrawings, v

A represents the main pipe, which is a`l1ollow metallic tube, made insections from four to six feet in length. The lower endvof the irstsection, when driven into the ground, is' provided with a suitable pointand screen, but as the 'same forms uo part of my invention, it is notnecessary to be fully described. Within said pipe I insert a cylindelyB,which isl providecliinternally atithe bottom with athread that takesinto a -like thread on the upper and cuter sideof'a hollow disk, C.Saiddisk is provided at or near the middleyvitb a shoulder, cutdiagonally toward the centre. The lbevel-led 'surface thereof isprovided with series of threads, that take into a like thread within theupper end of ring'D, the same being ut away to correspondwith theshoulder of disk C.

Said disk is provided with suitable packing L, between its uppershoulder and the lower end'of cylinder B,

which, Vwhen properly adjusted, forms afwater-tightjoint between thesides of said cylinder and theV sides ofthe main pipe. .Within saidcylinder B, and attached to the disk, is a globe or other suitablevalve, c, that operates in connection with a second or plunger-valve, e,withiril said cylinder, and connected to the handle o f the pump bymeans of rod d.

The operation of my `arrangement is as follows: As the main pipe isdriven to the proper depth, ring D (being so constructed as to closelyfill the cavity in the main pipe) is forced down into the tube to therequired.

depth, cylinder B is then inserted Within the tube, the thread at thelower end of disk C taking into the thread of ring D, and as saidcylinder is' given a number of rotating movements by means of a suitablewrench, which takes into notches cut in the upper end of said cylinder,the lower end of the same'comes in Contact with and against packing L ofdisk C, thus `forcing the saine outward' against the sides of the mainpipe A, whereby a waterftight joint is obtained, rod oZ- of valve e isthen connected to the handle of the pump, andthe well is complete. I

.As the manner of .allowing the water to enter the pipe forms no part ofmy invention, I have omitted its description, but I would briefly saythat it may be `admitted by perforating the lower end of the main pipe,or by raising the sa'me in any equivalent. manner.

Having thus described the nature and object of my-invention, what Iclaim as new, and desire to secure by Letters Patent, ig-

Cylinder B, provided with valves e and e, when s'o contructed as to becapable of being adjusted to any given point within the main pipe, incombination with ring 1),.disk C, and prevded with packing L, whereby a.water-tight joint may be obtainedvbetween the 'cylinder and the sides ofthe imain'pipe, substantially as and'lfor the purpose set forth.V
